Diesel or petrol?
If it has overheated in diesel too expensive - replace with 2nd hand motor
If petrol sometimes heads warp and can be replaced but pistons may need to be replaced as well.
If camshaft belt breaks it is rare to take out all cylinders, sounds more like severe overheating. if so pistons usually seize then let go but rings remain in grooves letting compression into sump and blows oil out extremities like timing case and rear main seal at gearbox . Can be tested by pouring 25mm of engine oil in cylinder then re-testing compression> if rings compression will increase. If valves the compression will not change. Good luck

diesels over heat from several things
1-- cooling system problems -- thermostat, fan clutch blocked radiator cores, head gasket
2-- fuel injection timing-- too far advanced
3--over fueling-- fuel control module -- faulty injectors --leaking seals
4--- dragging brakes
A simple test on the fan hub is when the temp is high , if you can stop the fan rotation , the hub needs replacing but as you have speed , the fan will not be operational as the wind speed through the radiator will overcome the fan requirement so that comes back to coolant flow
Blocked cores or core fin flaking off are problems here
lastly is the injection timing and rate of fuel flow are serious so I would suggest that you take it to a cummins specialist shop and have the fault codes read first as it could be a problem crank position sensor or injection timing control sensor

have you tried to check overheat gauge?? some temperature sensor? isn't that faulty?? I don't mean thermostat, but sensor...

is it really overheating, or gauge is showing overheating???

long time ago I had car that had same problem.... never overheated, but still signalized high temperature.....that time it was temperature sensor probably not compatible with correct one ....

Does the exhaust smell sweet -like ? Do you see steam after the warm-up period ? Its a Northstar engine ? That stuff doesn't just dissapear .. there something loosing it... How do you know theres no head issues ? Head gasket leaking into a cylinder, they are famous of that kinda stuff ...

May be the thermostat or even the radiator or A/C condenser in front of the radiator stopped up.

check the thermostat.
they are common to go bad

aluminum radiator
plastic top and base seal
tanks held in with crimps on aluminum radiator

find a local radiator shop to replace top seal and top plastic part
of that radiator
not as expensive as a new radiator

replace the thermostat

pressure is too much on that crack for any diy repair product

pop off hose at the wrong time =cook the motor

check for a blown head gasket, do a compression test on all the cylinders, they should all check out to about the same , if 2 are off you have a bad gasket

if you get an overflow through the resevior it's often times because the thermostat with stick shut causeing excess pressure. seeing is the car is not overheating this means that the trhermostat is opening but when you get that overflow it's sticking i would replace the thermostat as soon as possible to resolve this issue
